Key Lime Pi is an easy half-circle shawl crocheted from the neck-down. The ripple pattern has both written and charted instructions. This shawl is worked in two colors of fingering weight yarn. The high- contrast stripe pattern really shows off the ripple, though using one multi-colored yarn throughout would work equally well. Key Lime Pi is fast to crochet and is appropriate for beginners. There are 2 versions of the pattern, with US and UK terms. This pattern was tech edited by Chaitanya Muralidhara.
